A whole lot of websites link to www.cebik.com, the website for L.B. Cebik (callsign W4RNL) who has amassed quite a few articles on antenna design and construction.

I've recently developed an interest in getting signals from the International Space Station and the shuttle, so I'm looking at one of his designs to help me (I picked up some data transmissions the other night but didn't have the right software fired up to read what it said). One of his Moxon antennas might just fit the bill.
